Default My 149 speeds up

Last week I set my engine to the proper RPM's for high and low throttle. Now Im noticing that if I am on high throttle and I move the hyrdo lever forward a little to go slow, it keeps moving forward to high speed by itself. I was wondering if this is normal or another little project for me to work on? Thanks, Mark

Sounds like another project. Possibly trunion and or hydro linkage repair/adjustment time.

My 982 does that - takes me on a heck of a ride. I'm thinking that the linkage is a little loose.

You can tighten up the hydro lever. 149's had 2 different styles.
Early style has more of a clamp you can snug up.
Later style has a nut straight on the bottom of the shaft that you can tighten.
You will see once you get the tunnel cover off.

I looked under the hydro control shaft and their was a clamp that I tightened. I went too much the first time and it wouldn't move after that. I then loosened it a little and it seems to be holding just fine now in position. Thanks for the help!

Tagged for later.
The 109 I just bought does the same thing, except if you're sitting idle without the break on, it randomly takes off on it's own! It doesn't do it every time, but once it gets moving in either direction wether intentional or on it's own, the hydrostat lever will jump to full speed. Fixing that is the next thing on my to do list.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
